IMPROVEMENT IN GAS-UHANDELIER ATTACHMENT.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALFRED BLISS, of the city, county, and State of New York, have invented, made, and applied to use a new and useful Attachment for Gas-Chandeliers; and I do declare the following to be a full, clear, and correct description of my invention, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, in whieh- Figure 1 is a side elevation of my invention.

Figure 2 is a sectional view of the same.

Figure 3 isa. View of the same applied to a gas-chandelier.

In the drawings, like parts of the invention are pointed out by the same letters of reference.

The nature of my invention consists in the construction and operation, as more fully hereinafter set forth,

of a new and useful attachment for gas-chandeliers, for the purpose of conducting gas from the supply pipe to a drop-light, usually placed below the main or principal burners of the chandelier.

As at present constructed, .a drop-light is supplied with gas from the main or supply pipe by means of a pipe connecting the main or supply pipe and the drop-light, and inserted within the main or supply pipe, so that it may be moved freely up and down within it, to govern the position of the drop-light, the space between this pipe and the main or supply pipe being packed with any suitable material, so that what is termed a gastight joint may be formed. These joints, however, soon become worn and useless, and the result is leakage or escape of the gas, which proves a source of annoyance and expense to the consumer;

To overcome this difi'iculty, and to furnish the consumer with a ready and reliable attachment to conduct gas from the supply pipe to the drop-light, is the object of my invention, the construction and operation of which may be thus described: r

A is the framework of my attachment, provided at its top with the neck a, and at its bottom with the neck I), both of which have cut upontheir interior surfaces :1 screw-thread. Extending inward from the side of this frame is a hollow journal, 13, supporting the wheel or reservoir 0. This wheel or reservoir has aportion of its face cut away, and is provided with an opening, in which is inserted and held one end of a'flcxiblc tube, D. D is a flexible tube, formed of any suitable material, and made of any desired length, one end of which is inserted and secured in an opening in the wheel or reservoir C, while its opposite end is connected to the frame of the drop-light E. Upon the wheel or reservoir 0 are placed the flanged grooved plates of metal made to form, as it. were, continuations of the same. To these plates of metal F are attached the cords and weighted tasscls G. The hollow journal extends entirely through the wheel or reservoir, and the wheel is held in position upon the same by means of a. nut, y, as clearly shown in fig. 2, while the journal is held in position upon the opposite side of the frame A by means of the cap a: and a set-screw, z, the latter passing through the side of the frame and bearing against the cap 2:. [I shows a square rod of metal, inscrted'in the neck 6 on the lower part of the frame A. r'ithin this rod II is inserted and moves freely ,a second red, I, the lower end of which is attached to the frame of the drop-light E. This arrangement of the rods H and I allows the drop-light to be adjusted to any desired position, and serves to steady the attachment when applied to the chandelier. J is a cock upon the frame A.

Such being the construction, the operation is as follows: The attachment is applied to a chandelier, as shown in fig. 3, by placing the neck a over the end of the supply pipe, and turning the same until the connection between the pipe and attachment is firmly established. The rods II and I are then connected, as previously described, the one to the necleb and the other to the frame of the drop-light E, and the attachment is ready for use.

To supply the drop-light with gas, after the same has been adjusted to the proper position, the cock 3 upon the frame A is opened, and the gas enters from the supply pipe, as indicated by the arrow, passes through the gas way in the frame to the hollow journal, and enters the wheel or reservoir C through the openings 2'1, and is supplied to the iioxible tube D. One end of this tube is connected to the wheel or reservoir C, and the opposite end to the frame of the drop-light, and as the latter is drawn down, the flcxibletubc is unwound fromv the wheel 0, the weighted tassels upon the cords attached to the circular plates F, so that they shall be opposite to the tube D, serving to counterbalance the weight of the drop-light attachment. The gas is thus supplied to the droplight frame through the flexible tube, entering one of the arms S, and passing clown through the same to the light E. i

After use, the drop-light may be placed in its proper position by sliding the some up, the red I moving within the rod H, and the weighted tassels being depressed, and causing the flexible tube to be wound up on the wheel C.

Thus it will be seen that I produce an attachment for the supply of gas to a drop-light, which is open to none of the objections attending the present-mode. Again, all parts of the apparatus can be readily renewed, and the cost of making and adapting the same to a chandelier is but slightly in advance of the sliding-joint arrangement.

vHaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

I claim the combination of a wheel or reservoir, supplied 'with gas in any convenient manner, with a flexible tube, for the purposes indicated.

ALFRED BLISS.
